On this particular Immediately’s Home-owner Podcast, we’re speaking all about stone wool insulation with Dan Edelman, Rockwool’s Nationwide Enterprise Growth Supervisor.
What’s ROCKWOOL insulation?
Dan: ROCKWOOL insulation is a rock-based mineral fiber insulation comprised of Basalt rock and Recycled Slag. Basalt is a volcanic rock (considerable within the earth), and slag is a by-product of the metal and copper trade. The minerals are melted and spun into fibers.
ROCKWOOL merchandise include between 16% or 40% pre-consumer recycled materials depending on the ROCKWOOL manufacturing facility location.
The quantity of recycled content material is optimized to offer the perfect thermal, acoustic, and fireplace safety properties from ROCKWOOL merchandise, whereas nonetheless maximizing the recycled content material.
ROCKWOOL’s Historical past
Dan: ROCKWOOL firm started in 1937 in Copenhagen, Denmark, and the corporate expanded to the North American market in 1988.
So, our product is comparatively new to North America, however traditionally it’s been round for fairly a while now. We simply opened up a brand new superior manufacturing facility in Ranson, West Virginia.
All of our factories are zero waste-to-landfill, and since stone wool insulation is hydrophobic, we use recycled rainwater to chop it. Even our factories which can be wind- and water-powered are self-generating.
Yow will discover out extra about how our sustainable factories work on ROCKWOOL’s Sustainability webpage.
Benefits of Stone Wool Insulation
Dan: ROCKWOOL stone wool insulation is of course fire-resistant as a result of it’s constituted of rock. We don’t have so as to add any fireplace retardants or chemical compounds that improve flammability, so it’s by no means going to hold a flame and has zero smoke growth.
One other benefit is mildew resistance. ROCKWOOL stone wool insulation truly repels water. There’ll all the time be moisture within the air, particularly if you’re speaking about crawlspaces and attics.
With the ability to repel that moisture away and ceaselessly being a mildew and mildew-resistant product, it’s going to assist with the sturdiness of your wall meeting as properly.
Dan: ROCKWOOL insulation batts are available 16-inch on heart or 24-inch on heart by 47 or 48 inches lengthy, which is the proper measurement for insulating attics. They match completely between the studs, so that you get that full cavity insulation.
The 1st step when putting in attic insulation is to examine the present insulation. Ensure that there’s no moisture, mildew mildew, rodent droppings or rodents residing there. Rodents don’t primarily look after ROCKWOOL insulation.
After inspection, merely lay the batts down perpendicular to the joists, particularly if the prevailing insulation is just to the joists.
If the prevailing insulation is beneath the joists, you’ll wish to fill as much as the joist line so that you get extra steady insulation.
ROCKWOOL insulation usually has a 4.2 to 4.3 per inch R-value, so that you truly don’t want fairly as a lot to hit the upper R-value. Nevertheless, we have now merchandise with the next R-value primarily for attics.
What About Sound Insulation?
Dan: One of the best factor for sound insulation is density and mass, each of which ROCKWOOL has.
The opposite half to sound insulation is friction match, how tight it matches in that wall cavity. When you’ve got one space that you may’t insulate correctly, all of the sound goes by means of that one part and also you’re lowering that sound insulation.
